The poster claims MS rep told him "They never paid money to Rockstar" and that "Microsoft is totally happy about GTA IV being delayed".
What does Kotaku have to say?
"Word on the street was that Microsoft paid through the nose for GTA IV exclusive episodic content - to the tune of 50 million bucks. What an investment! The game has now been delayed (due to rumored PS3 programming probs) and won't make this Christmas. So you'd think that Microsoft would be pissed. Not so! Microsoft is so rich that the company doesn't care about silly things like selling games, right? Riiight. A Microsoft rep tell the NY Post's William Vitka that the delay will "allow gamers to focus on the other titles in this year's holiday lineup." But, glossy spin aside, Microsoft's gotta be annoyed. At the company's Xbox Holiday Press event earlier this week in New York, Vitka recalls this exchange he had."
